Arguments:

The size of the grain window in seconds. This value cannot be modulated. The minimum value is 3 sample periods. If you supply a smaller value, it will be rounded up to the minimum.

pitchRatio

The ratio of the pitch shift. Must be from 0 to 4.

pitchDispersion

The maximum random deviation of the pitch from the

pitchRatio .

timeDispersion

A random offset of from zero to

timeDispersion seconds is added to the delay of each grain. Use of some dispersion can alleviate a hard comb filter effect due to uniform grain placement. It can also be an effect in itself. timeDispersion can be no larger than windowSize .
